Idk I think its a major addation Or Reading Or Socail Studies Sorry tho
The equations are as follow,
A) HCN (aq) + H₂O (l) ↔ H₂CN⁺ (aq) + OH⁻<span> (aq)
B) </span>H₂O (l) ↔ H⁺ (aq) + OH⁻ (aq)
C) HCN (aq) ↔ H⁺ (aq) + CN⁻ <span>(aq)
D) </span>HCN (aq) + H₂O (l) ↔ CN⁻ (aq) + H₃O⁺<span> (aq)
E) </span>HCN (aq) ↔ H⁻ (aq) + CN⁺<span> (aq)
Answer:
<u>Option-D </u>is the correct answer.
Explanation:
When hydrogen cyanide is added in water it partially ionizes as follow,
</span> HCN (aq) + H₂O (l) ↔ CN⁻ (aq) + H₃O⁺ (aq)
Being weak acid it fails to completely dissociate into H⁺ and CN⁻ ions. In this reaction water is acting as a Bronsted Lowery Base and picks proton from from HCN and converts into conjugate acid (i.e. H₃O⁺), while, HCN converts into conjugate Base (i.e. CN⁻).
Answer:
F
EXPLANATION
Among the given elements fluorine(F)can not lose electrons easily because of its high electron affinity, high nuclear charge and high electronegativity.
Its b because it explains it better than a waterfall does
